I have an i5-4670k, a 650w power supply (currently using about 500w), a Z87 Extreme4 motherboard, two Cooler Master Sickleflow 120 case fans, and an aftermarket cpu fan, the Cooler Master Hyper 212 Evo. I want to overclock my cpu, but I don't know a good place to start. What should I bump everything up by? What should I stop at so that I don't over heat?
 
Solution
If you want to take it slow and steady, you could start with just slowly bumping the multiplier up a few notches at a time until you hit an unstable point without touching voltages, then back off until you're stable.

Or if you want, you could look around forums and see what the average is, and then set it to that and see how it works, and slowly move around from there.

Keep an eye on temps and such, make sure it's not overheating. Use prime95/intel burn test/occt/something similar to test for stability and what not.

set it to 42, see what voltage is required to make it stable if it is more than +0.01 then try 41. 43 should be achievable. As above watch the temps, if they are low enough (60ish) then consider a higher multi and a higher voltage. Do it on a throw-away copy of your OS, i.e. install nothing but the bare essentials. Then reinstall OS in case any of the crashes caused a problem.

Before doing anything read the sticky's on how to OC haswell.
